With increasing population and more competition for the use of water, wise water management is becoming more important. Spring and fall are transitional seasons when abrupt changes in temperature and precipitation may occur due to successive, fast-moving fronts separating contrasting air masses.

Averages are for Lambert-St. Louis International Airport, which is 13 miles from St. Louis. There have been occasional years when the soil moisture has been depleted, arid when rains have failed to replace the water lost by evaporation and transpiration for prolonged periods. Climate Zone Number 4 is defined as Mixed – Humid with IP Units CDD50ºF ≤ 4500 AND 3600 < HDD65ºF ≤ 5400 and SI Units CDD10ºC ≤ 2500 AND HDD18ºC ≤ 3000; Dry with IP Units CDD50ºF ≤ 4500 AND 3600 < HDD65ºF ≤ 5400 and SI Units CDD10ºC ≤ 2500 AND HDD18ºC ≤ 3000; Mixed – Marine with IP … © 2020 USATODAY, a division of Gannett Satellite Information Network, Inc. In the Ozarks, a large forest products industry is developing. Thus the length of growing season for these probabilities of freeze is much shorter and is more likely to be used for agricultural crops. Missouri generally has a variety of seasonal humid subtropical climate (Köppen climate classification Cfa), with cool winters and long, hot summers. A relatively small area in the south and southeast drains directly into the Mississippi outside the State through the White, St. Francis, and other minor streams. Hail also occurs in all regions and may occur throughout the year, but it is much less likely in winter. The metropolitan areas of St. Louis and Kansas City exert a significant and measurable effect on their climates. Nevertheless, several basic principles help to understand climatic differences in Missouri. Higher daytime temperatures of bare rock surfaces and higher albedo (reflectivity) of unvegetated surfaces may create distinctive environmental niches such as glades and balds.

The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. Annual Weather Averages in Cape Girardeau Regional Airport. For example, Missouri’s northwestern-most counties have a mean annual temperature of 50 degrees Fahrenheit and receive around 35 inches of precipitation per year. Missouri is divided into four planting zones: 5b in the north, 6a and 6b in the central regions and 7a towards the south. Get kids back-to-school ready with Expedition: Learn! May has the greatest number of days with hail. Occasionally, these produce some very heavy rains. Although winds are variable throughout the year, summer winds generally blow from the south and southwest and winter winds from the north and northwest.

Tropical cyclones and their remains can impact the state during this time of the year, contributing to area rainfall. Missouri is susceptible to the influences of cold Canadian air, of warm, moist air from the Gulf of Mexico, and of drier air from the southwest. But the boot heel counties have a mean annual temperature of about 60 degrees and receive nearly 50 inches of precipitation annually. Harris holds a Bachelor of Science in Mathematics from Penn State University; she taught high school math for several years and has also worked in the field of instructional design. Somewhat cloudier skies and more hours of very light precipitation may result, although the total amount of precipitation may not be greater than in non-metropolitan areas. Both mean annual temperature and precipitation exhibit gradients along this line. During the summer months the loss of water by evaporation and transpiration is high, and if rainfall fails to occur at frequent intervals, drought will result. Regional climates grade inconspicuously into each other.

the highest and lowest temperature readings during an entire month or year) calculated based on data at said location from 1981 to 2010.Official records for Columbia kept at downtown from August 1889 to December 1947, Columbia Municipal Airport from January 1948 to October 1969 and at Columbia Regional Airport since November 1969.Mean monthly maxima and minima (i.e. Facts. This would be about 6 million gallons per person in some of the more thickly populated areas, and about 36 million gallons per person in some thinly populated sections. Precipitation, usually sufficient for crops, varies from around 35 inches (890 mm) in the north and northwest to nearly 50 inches (1,270 mm) in the extreme southeast.

Climate can mean the average weather for a particular region and time period taken over 30 years. By the early 21st century African Americans accounted for more than one-tenth of the state’s total population, with the great majority concentrated in St. Louis and Kansas City.Since about 1980 the Hispanic and Asian communities have grown substantially. Missouri experiences regional differences in climates, but these differences do not have obvious geographic boundaries.

This area produces a large share of the cash value of all crops in Missouri each year.

Major crops are cotton, corn, and soybeans. Climate in Missouri. the expected highest and lowest temperature readings at any point during the year or given month) calculated based on data at said location from 1981 to 2010.Official records for Kansas City kept at downtown/Weather Bureau Office from July 1888 to December 1933; Downtown Airport from January 1934 to September 1972; and Kansas City Int'l since October 1972. Superimposed upon the basic statewide climatic patterns are local topographic influences that create topoclimatic, or microclimatic variations. Severe thunderstorms are a regular occurrence each spring, especially in May, with some storms producing hail and, inevitably, tornadoes. An average of about 30 tornadoes (3.8 tornadoes per 10,000 square miles) are reported in the state each year.
